AI Technical Summary

Benefits of technology

The invention is about creating a watch with multiple small displays that can be easily adapted to the space inside the watch case and has a thin profile. This is accomplished by using standard components that are commonly available and affordable.

Problems solved by technology

However, retrograde display mechanisms all occupy a large volume inside a watch case, and it is not always possible to accommodate them satisfactorily to offer the user a display with a logical juxtaposition of the various magnitudes displayed.

Embodiment Construction

[0018]The invention concerns a timepiece display mechanism 100 for a timepiece 1000, and more particularly for a watch.

[0019]This display mechanism 100 includes a least a first retrograde drive means 10 for a first display member 11 displaying a first magnitude, and a second retrograde drive means 20 for a second display member 21 displaying a second magnitude.

[0020]The invention is illustrated in the Figures for a non-limiting variant wherein the first magnitude is the minute and wherein the second magnitude is the hour.

[0021]First retrograde drive means 10 includes a first drive rack 12, which is arranged to exert, directly or indirectly, on a first wheel set 16 driving first display member 11, an opposite force to a resistance force exerted by a first return rack 17.

[0022]Second retrograde drive means 20 includes a second drive rack 26, which is arranged to exert, directly or indirectly, on a second wheel set 210 driving second display member 21, an opposite force to a resistance...

Abstract

A timepiece display mechanism including at least a first retrograde drive device for a first display member displaying a first magnitude, and a second retrograde drive device for a second display member displaying a second magnitude, the first retrograde drive device including a first drive rack to exert on a first wheel set driving the first display member, an opposite force to a resistance force exerted by a first return rack, the second retrograde drive device including a second drive rack to exert on a second wheel set driving the second display member, an opposite force to a resistance force exerted by a second return rack, wherein the pivot axes of the first drive rack and of the first return rack are remote, and / or the pivot axes of the second drive rack and of the second return rack are remote.

Description

FIELD OF THE INVENTION[0001]The invention concerns a timepiece display mechanism, including at least a first retrograde drive means for a first display member displaying a first magnitude, and a second retrograde drive means for a second display member displaying a second magnitude, said first retrograde drive means including a first drive rack arranged to exert, directly or indirectly, on a first wheel set driving said first display member, an opposite force to a resistance force exerted by a first return rack, and said second retrograde drive means including a second drive rack arranged to exert, directly or indirectly, on a second wheel set driving said second display member, an opposite force to a resistance force exerted by a second return rack.[0002]The invention also concerns a timepiece movement including such a display mechanism.[0003]The invention also concerns a timepiece, especially a watch, including such a timepiece movement, and / or such a display mechanism.[0004]The i...
